Project started in 01-01-2010 and coded with ❤️

This project is far from dead, but it requires revision... A new bootloader will be utilized for execution on 64-bit architecture. Additionally, new functionalities will be implemented:

• An integrated file system implementation supporting FAT32, NTFS, ext-versions, and much more.
• Multitasking extension for running many subprograms simultaneously.
• Extendable hardware driver slots for multitasking capability.
• An API for accessing all public kernel functionalities.
• A graphical user interface (possibly as a separate threading application). Many modern features will follow, but please be patient...

🤝 Bugs and help / improvements will be appreciated, please send them to (Yacine REZGUI) [email protected] and (Mario Ray Mahardhika) [email protected].

• GDT, IDT ( no problem... I hope )
• ISR ( currently, only page fault has additional handler )
• IRQ ( no problem... I hope )
• Console ( including simple command processing )
• Keyboard ( try to be US-std, but I don't know the keymap. Just guessing for now )
• Memory Manager ( needs testing )
• Speaker ( just for fun :-) )
• RTC ( seems wrong at PM, also for DayOfWeek )
• System calls
• Multitasking
• Filesystem ( perhaps FAT12 is the most obvious, or should we create one ourselves? )

• Successive Write(Ln) fails due to 103 IOResult
• Some inline assembler and assembler routines are missing register list, causing it to crash randomly (please test)

• Updated to FPC RTL revision 14499

• Not 📅 planned for now

• Some files are not used due to unusability ( multitasking & filesystem )

• Make sure you have working FPC installation ( try using latest 2.5.x snapshot if your version fails )
• Copy executables** under tools to a directory listed in your PATH ( or Path )
• Open Command Prompt ( start->run->cmd ), cd to fpos top directory, then type 'make'

• Adapt (Qemu or Bochs).bat to your Qemu / Bochs installation
• On Linux, you must change 'i386-linux-ld' in make.rules to 'ld'
